V packing seals are mould pression of rubber with fabric or rubber,normally NBR with fabric ,hard rubber for press ring and back-up ring ,hard plastic is also used for back-up ring .
V packing seals mainly apply to piston and piston rod of overload equipment,providing good avrasive reistance and stability as well as preventing extruding seals out of the gap.
Moreover,it can provide best sealing even under hardsh condition,like temperaturechange, unexpected pressure ,axial/radial vibration. etc.
V-Packings are also used in various Oilfield Downhole equipment such as various Valves etc. V-Packings are extremely suitable for usage in medium to heavy duty applications. Vee Packings accept low and high pressure while operating in the most extreme conditions and also if there exists any misalignment between the sealing gaps.
The hinge-line action of Vee-Packings that enables immediate reaction even to minor pressure changes is very distinctive and exclusive to a Vee-Packing design. Each individual lip of a Vee-Packing set reacts independently to pressure thus effecting aseal automatically. In case of multiple lip configurations, pressure is automatically distributed thus effecting a seal along the shaft. Vee-Packings also premit automatic reaction to shocks from high pressure and overloads.
The Vee-Packing is a combination of Base Seal, the Vee-Ring at the center and the Pressure ring. The Vee-Ring is the main seal that can retain high and low pressures while the base seal supports the center ring from getting extruded during high pressure applications. The Pressure Ring helps in retaining the Vee Packing profile and distributing pressure equally.
